FURNACE-.CASING-ATTAOHING MEANS.

Application filed February 13, 1922. Serial No.- 536,231.

To all whom; it may concern Be it known that I, DON V. RUNNION, a citizen of the United States. and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Furnace-CasingAttaching Means, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

This invention relates to improvements in furnace casing attaching means.

'I-Iot air furnaces are usually formed in part of sheet metal casings connected along their front edges to a cast metal front or face plate which carries the doors to the fire pot, ash pit, etc. Bolts arensually used to connect the parts together, but considerable difliculty is experienced in connecting the thin sheet metal casing edge to the cast metal front due to the fact that it is desirable to position the nuts and the ends of the bolts within the casing and it is difficult to hold the nuts while drawing the parts together. I V

7 It is one of the objects of the present invention to overcome the before mentioned objectionable features and provide a furnace casing attaching means which may be easily connected to the casingand which will permit the parts to be quickly, drawn together.

A further object of the invention is to provide a furnace casing attaching means which is of simple construction, is strong and durable and is well adapted for the purpose described. I

With the above and other objects in View, the invention consists of the improved fur nace casing attaching means and its parts and combinations as set forth in the claims and all equivalents thereof.

In the acompanying drawing in which the same reference characters indicate the same parts in all of the views: v t

Fig. 1 is a side view, partly in section of fragmentary portions of a furnace provided with the improved furnace casing attaching means; and

ig.2is a horizontal sectional view taken on line 2-2 of Fig. 1.

1 Referring to the drawing, the numeral 5 indicates a portion of the outwardly angled cast metal front or face plate, 6 a portion of the inner sheet metal casing, and 7 a portion of the outer sheet metal casing connected thereto by the improved attaching means 8. Said means comprises a bolt 9, a nut 10 anda socket member 11. The socket member 11 is formed of sheet metal and is provided with a flat portion 12 having edge tangs 13 i which extend inwardly through tank open. lugs 14 in the casing '7 and arebent over to firmly attach the member to the casing adjacent its front edge as clearly shown in the drawing. The member 11 is also shaped to form an inwardly bulged portion 15 having afiat front end part 16 provided with a bolt opening 17 for receiving the bolt 9. The bulged portion 15 forms-a socket which is of elongated form in longitudinal alinement with the bolt to accommodate comparatively a long stove bolt. and the flat front end and outer portions wil'l accommodate the nut 10 and hold it against turning when threaded on the bolt.

The face plate 5 is of the recessed type so that the outwardly flanged portion 5 extends at an angle to the front edge of the inner casing and is formed with an opening 17 to receive the shank of the bolt. I l

The inner casing 6 may be fastened to the face plate in any manner desired.

It is of course understood that a number of the attaching members are used on each side edge of the face plate adjacent the outer flanges 17 in connecting the casing member thereto, and other means may be used for drawing the edges against said flanges 17. I f

As the bolts are comparatively long they may be easily'threaded into the nuts held in position in the sockets and the parts quickly drawn together. -Furthermore, the bulged portion of the socket member extending inwardly through the casing opening relieves the tangs of allstrain as the pull 1 comes directly against the edge of the casing portion forming the opening.

From the foregoing description it will be seen that the furnace casing attaching means and having projecting edge tangs for connection with a furnace casing, a nut posi llO tioned within the socket adjacent the bolt opening and a bolt extending through the opening and threaded into the nut.

2. I A furnace casing attaching means, comprising a piece of sheet metal shaped to form a socket With a flat end provided with a bolt opening communicating with the socket, said piece of metal having a fiat outer portion with tangs projecting from the edges thereof for attachment to a furnace casing, a nut within the socket and resting against the flat end portion, and a bolt extending through the opening and threaded into the nut,

3. In combination with a furnace casing having an opening and a face plate flange provided with. a bolt opening, of a means for connecting the casing to the flange in overlapping engagement, comprising a member formed with a bulged out portion which extends inwardly through the casing opening and provides a socket approximately entirely within the casing, said: bulged portion having a bolt opening within the casing, a nut within the socket, and a bolt extending through the face plate flange bolt opening and within the casing and through the bolt opening of thebulged portion and threaded into the nut.

4:. In combination with a furnace casing having an" opening and a face plate" flange provided with a bolt opening, ofa means for adjustably connecting the casing to the flange in overlapping. engagement, comprismg a piece of sheet metal shaped to form a bulged out portion having a socket and" which bulged out portion extends inwardly through the casing opening, said piece of metal having edge tangs which extend through the casing to connect the piece of metal to the casing and the bulged portion having a bolt opening within the casing, a nut within the socket, and a bolt extending through the flange bolt opening and within the casing and through the opening of the bulged out portion and threaded into the nut.

Intestimony' whereof, I afiixmy signature.
